Question
The objective of this experiment is to demonstrate how light intensity affects photosynthesis. What inference can we make from observing this experiment? [B.2E]Select one:a.Carbon dioxide gas is being collected in the test tube.b.Glucose is dissolved in the water.c.Oxygen gas is being collected.d.Water is produced in photosynthesis and is collected in the tube.
Solution
From the given options, the most likely inference we can make from observing an experiment demonstrating how light intensity affects photosynthesis is that "Oxygen gas is being collected".
Here's why:
Photosynthesis is a process used by plants, algae, and certain bacteria to convert light energy, usually from the sun, into chemical energy in the form of glucose. In this process, organisms use water (H2O) and carbon dioxide (CO2) to produce glucose (C6H12O6) and oxygen (O2).
The general equation for photosynthesis is:
6CO2 + 6H2O + light energy = C6H12O6 + 6O2
This means that as photosynthesis occurs, oxygen is produced as a byproduct and can be collected and measured in an experiment. This allows us to observe and infer the rate of photosynthesis under different light intensities.
So, the correct answer is c. Oxygen gas is being collected.
